In North Rhine-Westphalia, Germany, the Halingen waterworks will be expanded to include a new drinking water treatment plant by 2025. The Zemdrain® formwork liner was supplied to meet the high hygiene requirements for this structure.
Drinking water is invaluable. For this reason, strict quality standards are imposed on the concrete components used in the construction of drinking water tanks. Waterworks Westfalen, which operates six waterworks in North Rhine-Westphalia, Germany, among others, is expanding the Halingen waterworks by 2025 to include an advanced treatment plant in order to be prepared for the removal of any undesirable substances that may occur in the future.
In order to avoid coating and ensure the longevity of the drinking water tank, the walls and supports of the structure were concreted with Zemdrain® formwork liner. MAX FRANK previously supplied Wasserwerke Westfalen with the Zemdrain® Classic TW formwork liner for the Hengsen waterworks in 2020/21. The quality of the concrete surface also impressed the client in this project.
Zemdrain® creates a virtually void-free surface and improves the concrete's ability to resist chemical attack by reducing the water-cement ratio and surface porosity. This makes the concrete harder, denser and more resistant. At the same time, potential cavities in which microorganisms and algae can accumulate and multiply are avoided. This significantly increases the service life of the concrete structure.
For the highest quality standards for potable water applications the test certificates for Zemdrain® CPF liner are available for the DVGW requirements (W 270 and W 347). Now new and additional - with extended duration in formwork status. The results of the additional drinking water tests "with extended duration in formwork status on" were convincing: there was no fibre adhesion to the concrete and therefore a very good concrete surface quality. The tests were confirmed by the renowned Institute of Hygiene in Gelsenkirchen, Germany.
